I pull the trigger on my blower and the light on the battery turns green but nothing else happens. It’s the first nice day of the year and I wanted to get a jump on getting the lawn ready, but when I tried to run my backpack blower the fan didn’t spin. I tried the battery that came with it. Put it in the charger in case it lost charge over the winter. Tried the battery that came with the string trimmer and the one from the mower. Is there some troubleshooting I can try?
